My organization’s M&A Integration team is fairly small with me essentially program managing a few full-time members from legal, operations and finance with part-time assistance from HR, marketing, services, client experience, etc. We are actively exploring team expansion to keep up with the tempo of transactions and growing deal complexity. What permanent roles or positions do you feel are vital to ensure integration success and why?
Hi Judith.
Thanks for your post.
It really depends on the deal volume you are facing , size and complexity.
However, considering that the team is getting involved from DD, I think you could consider something as:
– IMO Director – the person that leads the full Integration team across deals
– IMO Leads – FTEs that are fully dedicated to one or more deals at time, coordinating the different workstream, from integration blueprint to Day 1 Planning and Execution to Day 100 to transition to BAU
– IMO Finance Lead – FTE to be fully dedicated to the Finance integration working side by side with the Finance WS Lead – Finance, independently of deal type almost always require full integration
– IMO Comms and Change Management – dedicated to E2E comms and change management, cutting through different WS and working side by side with WS Leads to ensure standardised comms approach and consistent messages
– IMO Synergy Lead – person dedicated to the synergy case, reviewing the deal synergies, validating, adjusting, identifying more synergies and working with IMO leads to translate synergies into actionable plans and have tracking in placeFor more roles (even Finance and Comms) you could look to equip people from the functions to be ready to execute integrations and be dedicated to that while sitting outside of your IMO (it’s an alternative).
It is an interesting question and one that we have grappled with as our M&A activity isn’t consistent and can span geographies.
The approach we have therefore taken is to maintain a small core team whose job is to make the functions responsible for the integration of their respective areas and the core team is the glue that provides the best practice, the framework, the continuity.We therefore have a core team consisting of the following roles and drive the business to assign workstream leads per integration to cover their areas.
– Head of M&A Integration overseeing the Playbook and the Programme Managers
– Integration Programme Managers (usually 1 covering each region)
– Integration PM (usually 1 per integration)
– Business Change Manager
– PMOPart of the reason for this is that we find resistance when we centralise too much and prefer to make the functions more responsible.
Yes, it really depends on the size of the deals, how frequent they occur (1 a year/multiple a year), on-site support (if the acquiring organization is global) and complexity. Again, if the org is global, boots on the ground are a necessity. Bringing in outside parties in those jurisdictions is sometimes required, especially in the finance realm with all the different criteria for local and IFRS books.
For the organization I work in, we currently do not have a dedicated team of resources, which we need/are trying to establish. Each integration/acquisition has a group chosen at the facility/plant level, and we are building a team out of the Corporate Office that has been newly established to work in conjunction with the plant team.Current Structure is as follows:
Plant Team: Project Champion/Sponsor, Operations, Materials, Finance, HR, Sales, Quality (these are the Leads for each function, aka Matched Pairs with the new Org).
Corporate Team: Corporate Controller, Technical Accounting Specialist, Tax/Treasury, Consolidations, M&A Integration – Finance, Legal, Corp DevelopmentThe biggest challenge for us is also what Daniel noted, since M&A activity isn’t consistent and can span across the world, there is always a bit of pushback in standardizing a team. The organization is afraid that team won’t be busy full time (though that never seems to be the case). I believe since we do not always have a core team set, we have problems in communication, details, and large transactional issues can occur.
Hi Judith – great question, and I really like the perspectives shared here.
Building on Miguel, Daniel, and Kristi’s points, I’ve found that the most effective model is a small, high-impact core IMO team complemented by strong functional ownership. In terms of must-have permanent roles, here are some selective roles that we have:
Integration Program Lead(s): Critical for end-to-end accountability—from diligence through Day 1 to stabilization. They act as the “single throat to choke” across workstreams.
PMO / Governance Lead: Ensures structure, cadence, risk tracking, and consistency across deals—especially important as complexity and volume increase.
Finance / Synergy Lead: Beyond just finance integration, having someone focused on synergy validation, tracking, and realization is key to actually delivering deal value.
Change Management & Communications Lead: Often underestimated, but essential for aligning stakeholders, reducing resistance, and maintaining clear, consistent messaging across functions.
What I’ve seen (and aligns with the course material) is that gaps in communication and change management are often the biggest drivers of integration challenges—not technical execution.
Given your current lean structure, even adding 1–2 of these roles (especially PMO + Comms/Change) can significantly improve the integration office and outcomes, while still leveraging functional teams for execution.
Curious to know if you are seeing more challenges on the execution side or stakeholder alignment side today?Love this question! We are building out our PMO as well.
In a small but growing integration team like yours, I’ve found success usually comes less from adding generalists and more from strengthening a few core, clearly defined roles that improve coordination and accountability.
A strong Lead, Strategic Initiatives is essential—not just for tracking plans, but for managing interdependencies and driving fast decision-making across legal, finance, ops, and HR.
A dedicated Change & Communications lead is also critical. This role helps shape consistent messaging, align stakeholders, and reduce friction between legacy and acquired organizations—especially important in more complex or cross-border deals.
I’d also add a Finance/Value Tracking partner focused specifically on synergy delivery and ensuring integration efforts stay tied to business case outcomes, not just execution milestones.
Overall, these roles help shift integration from reactive coordination to a more structured, repeatable value delivery engine.
I love this question because it showcases thoughtful approach to deal value creation. I’ve unfortunately been in a spot where my previous role in PMI as an FTE was eliminated and fully outsourced. In my job search, I found many companies who were looking to hire one singular person to further the company’s inorganic growth strategy by executing on all PMI themselves across core functionality (usually in B2B SaaS companies, so focus was Finance HR and Technology including both DD and integration responsibilities) to make the company an intended ‘serial acquirer’, often stating in the job description between 8-10 closed transactions a year. Those positions scared me away because it showcases a complete misunderstanding of the work involved.
I am of the opinion that, as companies scale, there is a layer cake of focus that needs to be applied, almost like Maslow’s hierarchy of needs. The PMI team should have centralized governance and leadership to help project and program manage at a high level while maintaining strategic focus on the inorganic growth strategy brought by Corp Dev. From there, staffing should focus beginning on the inside out. Maslow’s needs are (1) physiological needs (air / food / water / shelter), (2) safety needs, (3) belonging needs, (4) esteem needs), and (5) self-actualization needs. If we map these to staffing and organizational development within the PMI space, the focus is fairly 1:1:
– Physiological Needs: this is satisfied by sales integration focus. Sales is your food and you gotta eat to survive. If Sales is treated sandalone or as a function of Finance then you’re good. If Sales has no oversight you’re probably not good. Sales is typically staffed already, but you may need specific program groups to help the Sales team reach their full value. L
– Safety needs: this comes from (1) Finance and (2) Legal. Finance helps the company to protect itself from itself, protect itself from outside influence (customer or vendor cashflows, regulatory requirements, etc.), and ensure general rules and security. For Finance, you’d need people to help with FP&A, Controllership, Treasury, Intercompany, O2C, P2P, etc. Focus for staffing would then be based on volume of deals, target integration timeline and archetype, etc. This would be a primary area for FTEs initially, but may substitute with consultant work to deliver speed to value if that’s a concern. Legal protects the company’s best interests at all times, and may be staffed already within corporate counsel or require outside counsel depending on the working capacity and knowledge set of your org’s counsel.
– Belonging needs: this is HR through and through. It may be good to have this staffed with FTE, but can probably be substituted without if your HR is a shared service and structured with a standard staffing plan of x HR reps to y employee resources. In any instance, the overreaching M&A integration team should help set general guidance on retained culture vs integrated culture, retained comp & ben vs integrated comp & ben, etc. If those rules are all in place, then HR can be generally straightforward, and then just flex up with staff aug resources as needed depending on any one deal size or overall deal volume.
– Esteem needs: this is where things start to get tricky. Esteem can manifest itself in how a company sets it’s corporate identity, and may leak into various departments. Depending on your org’s needs, if you’re just looking to integrate but not have a common identity, maybe you don’t need to focus here at all. If you’re very focused on brand reputation, etc, then you may need to staff for things like Brand Marketing, corporate technology, GTM/ sales marketing, or anything else that you believe provides your corporate identity and ‘secret sauce’.
– Self-actualization needs: this is (although listed last), a component of your main PMI governance team. But instead of being focused on standing up the PMI function or helping to execute on deals, it’s a group more focused on how to do deals better, how to create more value, and how to better align cross-workstream to recognize full potential. This group helps to deliver the “fly” aspect of crawl / walk / run / fly frameworks.I think that a company’s maturity across this framework starts first by addressing these needs individually by people doing them off the side of their desk, to then start to have dedicated FTEs doing some of the activities, to then having whole groups and departments focused on these areas. But very much in a waterfall fashion, as there’s no need to address self-actualization if you don’t even have your head wrapped around all aspects of solid financial integration.
Hi Judith, in my experience, PMI success relies on key dedicated roles, not just checklists. Crucially, an Integration Leader must engage before due diligence, supported by a Permanent Integration Team and a Dedicated Finance Lead for Day-1 pressures.
Equally vital are Cultural Ambassadors, Legacy Leaders for continuity, and Customer Relationship Managers to protect revenue. Securing early, dedicated Workstream Leads ensures execution doesn’t stall.
What we lacked in an earlier integration was a heavy weight executive with a mandate as an IMO director. Many of us were operators that lacked the mandate to make decisions without ceo or c-level approval, adding a ton of meetings, explaining, and time, causing frustration with the target company.
As deal volume and complexity increase, I believe the permanent team should include an integration program leader, functional workstream leads, and dedicated change management and communications support. I would also consider making HR a full-time member because talent retention, leadership alignment, organizational design, and culture can significantly affect integration outcomes.
The permanent team does not need to include every subject-matter expert. A strong core team should establish repeatable processes, clarify accountability, track risks and synergies, and engage part-time specialists when needed. This structure provides consistency across transactions while remaining flexible enough to scale based on the size and complexity of each deal.
While the nature and complexity of the merger and integration activities should drive the roles and IMO structure, I think there are a few key functions that should be considered. First, a function that oversees the governance is critical. This would include aspects such as program and project management, analysis, benefit tracking, and reporting. This is likely the biggest function within the IMO. Other supporting functions that I would recommend would be a team to focus on the management of the many changes arising from merger activities (separate from any BAU change management functions), and lastly the required subject matter expertise or a function that partners closely with the SMEs to ensure that impact on the business and customers is managed and decisions made are done so in a way that limits negative impacts and fosters the desired benefits of the transaction.
I would separate a small permanent IMO core from different functional experts background. The key permanent roles are IMO lead(s), dedicated integration programme/PMO capacity, a People, Change and Communications lead, and a Value Capture/Synergy lead. Finance can be combined with value tracking in a lean team, while legal and operations remain functionally accountable.
Given your current setup, I would first add dedicated PMO capacity, then a People/Change lead, followed by synergy-tracking support. The IMO should provide governance, decision rights, standards and continuity; the functions should own execution.
I think the answer depends largely on the scale of expansion. If you are adding only 1-3 FTEs, I would prioritize an experienced Integration Manager/PMO lead and a dedicated functional integration resource (often HR or IT) to strengthen execution capacity and governance. If you are expanding by 5+ FTEs, it becomes worthwhile to build a more formal Integration Management Office with dedicated workstream leads for HR, IT, Communications/Change Management, and Synergy Tracking, as complexity tends to grow exponentially with deal volume rather than linearly.
